Should you help your friend get married?

It's still not widely acceptable in India to marry people from other "castes", at least in the rural areas where we are from. I have known my friend for over 20 years and he's with his girlfriend for over 15 years, but still their parents didn't want them to get married as they are from different castes.

But almost 2 years ago, the friend reached out that they are willing to get married secretly in the court without letting there parents know. They were not at all ready to take the risks of living apart from each other, and letting parents know would have been a big risk as the parents in India are even known to forcefully marrying their children (mostly girls). So their plan was to get married and secure the marriage certificate first, and then only let their parents know so that they can't forcefully marry them to someone else.

He asked for my help as an eye-witness for the marriage, and I couldn't say no. We all went to the court and I signed as one of the eye-witnesses and they got married. However, they were staying separately in their own cities even after getting married.

They were planning to let their parents know slowly, but there must have been some information leak from somewhere and now the girl's parents are suspecting both of them. They know the guy separately, but now suspecting that he might be the guy the girl tells about.

And since both their parents know me as well, it has become an interesting intertwined situation.

I am not sorry for what I did, though.
